Purpose : We aim to characterize clinical and radiological results of arthroscopic microfracture in patients with focal full-thickness cartilage defects of the medial femoral condyle in the osteoarthritic knee.Materials and Methods : Our study population consisted of 76 patients (17 men and 59 women) with the mean age of 60.6 years . All patients underwent partial (n = 60) or subtotal (n = 16) meniscectomy. Follow up period was a minimum of 36 months. Group I included 38 osteoarthritis patients who were aged over 50 years and presented with symptomatic medial meniscus tears and focal grade IV full-thickness articular cartilage lesions. Medial meniscectomy and microfracture on the medial femoral condyle were performed on the Group I patients. The results of Group I was compared to 38 osteoarthritis patients (Group II) who were selected from more than 100 patients who underwent only meniscectomy for medial meniscal tears accompanied with a focal full thickness cartilage defect in the medial femoral condyle.Results : At the time of the three-year follow-up, a total of five failures (6.6%) were reported: four Group I patients and one Group II patient . The two groups showed no significant difference in the Lysholm score, the Tegner activity score and the visual analog pain scale at three years after surgery. However, at the time of three months follow-up, Group II showed significantly more improvement in Tegner activity and the visual analog pain scores compared with Group I. Younger patients (under 60 years old) scored better on visual analog pain scale than did older patients regardless of their treatment group. Conclusion : We conclude that, in osteoarthritis patients with symptomatic medial meniscus tears, arthroscopic microfracture surgery for a focal full thickness cartilage defect on the medial femoral condyle did not confer any additional benefit to meniscectomy.
